How To: Create a Mobile Live Streaming App | Wowza CREATING A MOBILE LIVE-STREAMING APP: HOW DO I GET STARTED? You’ve decided that you need mobile live-streaming capabilities to allow your users with iPhone and Android devices to capture and send a live video stream from anywhere with a mobile connection. How do you get started? This guide presents options, best practices, and examples for creating a mobile live video streaming app of your own or integrating live-streaming capabilities into your existing mobile app. MOBILE BROADCASTING GOES MAINSTREAM Worldwide, the dominance of mobile devices continues to drive technology’s evolution. Mobile broadcasting is exploding, and it’s not just for social media. Mass-market apps such as Periscope have received major attention, but the uses beyond that are wide-ranging, from niche apps such as G9MD that are targeted to specific professions to streaming of live sporting events, insurance-claim damage reporting, aerial reconnaissance via drones, crime-fighting citizen journalism, and much more. Clearly, live streaming from mobile devices has moved from the new and different to the mainstream and bridged the gap between business and pleasure. If organizations want to capitalize on this movement, they need to act quickly and utilize proven technology to fully leverage mobile live video streaming. YOUR END-TO-END MOBILE STREAMING OPTIONS A successful mobile live-streaming app requires a reliable end-to-end streaming workflow, from video and audio capture to encoding, transcoding, packaging, delivery, and playback. The right approach for you depends heavily on what pieces you already have, how fast you need to go to market, whether you need custom branding or functionality, and what developer resources you have available. No matter which option you choose, Wowza Media Systems™ can provide some or all of the end-to-end mobile live-streaming technologies. The image here illustrates the major options we’ll cover. OPTION LIVE EVENT CAPTURE PROCESSING SCALING & DELIVERY PLAYBACK 1 OTT Devices Camera Encoder • End-to-End Managed Live Streaming tv • Built on Wowza Streaming Engine • Automatic Scaling to Any Size Audience • Multi-Cloud, Multi-CDN Adaptive Bitrate Mobile Devices 2 OR Third party Mobile App iOS Pay-as-You-Go CDN Edge Servers Other Devices 3 • Software-Based Media Server • Deployed on premises or in the Cloud • Complete Server-Level Control • Highly Abstracted Architecture CAPABILITIES API 4K Resolution Live Video Audio Only REST / Java DVR Transcoder Security / DRM Global Load Balancing Scalable Adaptive Bitrate Closed Captions Multi-Protocol © 2016 Wowza Media Systems™, LLC. All rights reserved. MOBILE LIVE-STREAMING WORKFLOW OPTIONS & DESCRIPTIONS OPTION SCENARIO DESCRIPTION You already have one or more video cameras and a hardware or software encoder 1 Use your existing camera(s) and encoder for compressing the outgoing video and audio. You already have a mobile encoding app and now you need to deliver streams 2 Use a third-party mobile encoding app to viewers. You plan to use the available Wowza GoCoder app as is to meet your Use the Wowza GoCoder™ mobile capture and 3 live-streaming requirements, white-label it, or leverage the available SDK to encoding app or SDK add the ability for users to send a live stream from your existing mobile app. The options in the table here map to the three streaming workflows shown in the graphic. Choose the one that best matches the scenario you plan to enable. In the following sections we’ll explore how to get up and running with your chosen option for mobile live streaming. (Each of these assumes someone is actively managing the delivery of streams to viewers and is responding to requests to stream live incoming content from a remote [mobile] encoder.) OPTION 1 USE YOUR EXISTING CAMERA(S) AND ENCODER If you’ve already been streaming with one or more cameras and a software or hardware encoder (or an IP camera with built-in encoder) and are now trying to reach viewers on their mobile devices, take the following steps to complete your workflow. 1 Determine which streaming formats your encoder can deliver. The H.264 video and AAC audio codecs and the RTMP and RTSP streaming protocols are common for compression and delivery. 2 Decide whether to use Wowza Streaming Engine™ media server software or the Wowza Streaming Cloud™ online service for delivery of streams. 3 Determine which media players and devices you will be targeting as you get started. (Common ones include JW Player, Flowplayer, Shaka Player, THEOplayer, and Radiant Media Player.) • We often recommend JW Player as a great any-screen option, including both in-browser playback support and mobile SDKs for iOS and Android devices. • Many other player technologies are available, including open source options such as the Google Shaka Player for MPEG-DASH streaming. • On Wowza Streaming Cloud, you also have the option to use the provided any-screen player, either on a free hosted web page that Wowza™ provides and you brand, or on your own web page. BEST PRACTICE You can test multiple players and streaming formats directly on the Wowza Test Players page to ensure everything works as planned before you take your app live. 4 When you’re ready to send a stream from the existing encoder, log into your Wowza server or cloud account, then follow the five-step setup wizard in Wowza Streaming Cloud or this tutorial for Wowza Streaming Engine, publish your live stream, set up playback to your web page or desired player, and share a link to your stream with your audience via social media, your website, email, etc. © 2016 Wowza Media Systems™, LLC. All rights reserved. OPTION 2 USE A THIRD-PARTY MOBILE LIVE-STREAMING APP Numerous third-party mobile apps for iOS and Android can encode and send live streams to Wowza Streaming Engine and Wowza Streaming Cloud for any-screen distribution. If you’ve found or built an app you like, follow these steps to share your live streams with viewers. 1 Determine which streaming formats your mobile live-streaming app can deliver. The H.264 video and AAC audio codecs and the RTMP and RTSP streaming protocols are common for compression and delivery. 2 Note that some mobile live-streaming apps don’t have support for source authentication—if yours does not… BEST PRACTICE a. Determine the risk of an unauthorized person sending an unapproved stream for delivery. b. Determine how risk-averse you are and, if the risk seems sufficiently high, consider switching to a mobile app that supports RTSP or RTMP authentication. 3 Decide whether to use Wowza Streaming Engine media server software or the Wowza Streaming Cloud online service to deliver your streams. If you’ll be using a CDN (content delivery network), edge servers, or services such as YouTube Live to scale out your streaming, assign the appropriate stream targets. 4 Determine which media players and devices you will be targeting as you get started. (See the Best Practice note on the previous page.) 5 Provide mobile users with links to download the mobile live-streaming app you’re using. 6 When a mobile user contacts you with a real-time request to broadcast a stream from his or her location, log into your Wowza server or cloud account, then follow the five-step setup wizard in Wowza Streaming Cloud or this tutorial for Wowza Streaming Engine, publish your live stream, set up playback to your web page or desired player, and share a link to your stream with your audience via social media, your website, email, etc. REAL-WORLD Before Wowza offered the Wowza GoCoder Private Label and SDK options to customers, Periscope built its own live-streaming app for delivery to Twitter feeds, delivering the streams from Amazon EC2 instances EXAMPLE running Wowza Streaming Engine. OPTION 3 USE THE WOWZA GOCODER MOBILE CAPTURE AND ENCODING APP OR SDK Wowza GoCoder gives you three ways to offer your users an elegant mobile live-streaming app. WOWZA GOCODER An app available for free on the Apple App Store and Android Play Store WOWZA GOCODER PRIVATE LABEL An offering that allows you to work with Wowza to design a version of Wowza GoCoder with your own branding and configuration settings WOWZA GOCODER SDK Wowza GoCoder in Use A software development kit that simplifies mobile app development for iOS and Android © 2016 Wowza Media Systems™, LLC. All rights reserved. Use the Wowza GoCoder mobile app on Apple iOS and Android devices to encode and stream live events in HD on the go, from any location to any screen, in real time over Wi-Fi, 4G, or 3G. Users can also control Wowza GoCoder from their Apple Watch or Android Wear devices paired with iOS and REAL-WORLD EXAMPLES Android devices 1 Decide whether to use Wowza Streaming Engine media server software or the Wowza Streaming Cloud online service for delivery of streams. 2 Determine which media players and devices you will be targeting as you get started. (See the Best Practice note under Option 1 earlier.) 3 Provide mobile users with links to download Wowza GoCoder from the Apple App Store and Ensemble Video‘s EnsembleLive app for the Google Play Store. iOS and Android, built with the Wowza When a mobile user contacts you with a real-time request to broadcast a stream from his or GoCoder Private Label offering, enables 4 her location, log into your Wowza server or cloud account, then follow the five-step setup business and education customers to wizard in Wowza Streaming Cloud or this tutorial for Wowza Streaming Engine (selecting easily record content directly to an Wowza GoCoder as your video source), publish your live stream, set up playback to your web Ensemble Video media library while live- page or desired player, and share a link to your stream with your audience via social media, streaming video and audio in real time your website, email, etc.
